Clinical trial failure risk - Phase I/II programs carry 85-90% historical failure rates in oncology, with safety issues or lack of efficacy potentially terminating programs and eliminating enterprise value
Regulatory pathway uncertainty - allogeneic cell therapy manufacturing and quality standards evolving, with FDA guidance potentially requiring costly additional studies or manufacturing changes
Competitive obsolescence - rapid innovation in CAR-T, TCR-T, and tumor-infiltrating lymphocyte therapies could render MT-TC platform non-competitive before commercialization
Reimbursement uncertainty - even with approval, payer willingness to cover novel cell therapies at profitable price points remains unproven outside CAR-T in large B-cell lymphoma
Well-funded competitors with allogeneic platforms (Allogene, Fate Therapeutics, Cellectis) advancing similar off-the-shelf approaches with larger clinical datasets
Autologous CAR-T market leaders (Gilead/Kite, BMS/Juno, Novartis) expanding into solid tumors and earlier-line settings, potentially capturing addressable market before Marker reaches approval
Academic medical centers developing competing T cell therapies with institutional backing and faster patient access through investigator-initiated trials
Cash runway risk - pre-revenue biotech with negative $0.0B operating cash flow requires periodic equity raises, creating dilution risk for existing shareholders
Financing risk - ability to raise capital depends on market conditions and clinical progress; failed trials or risk-off environments could force unfavorable financing terms or strategic alternatives
Going concern risk - if clinical setbacks coincide with inability to raise capital, company may face wind-down scenario with minimal recovery for equity holders
